Hey everyone,
I have been having this problem over the last two years mostly when the temp is warmer outside. The problem came back about two weeks ago; after driving about 45min on the highway, i parked at a store and was there about 5-10mins. When I came back and put the key in the ignition i heard the beeping noise and went to crank the engine. When I did everything just died, no lights on the dash at all. I was pretty surprised but I knew what I had to do. I opened the hood and wiggled the negative terminal connection on the battery and came back and it turned on just fine. I have been having this problem occasionaly over the last two weeks. Should the loop around the terminals be really tight, not allowing any wiggle room? Do you think that is the only problem?
Thank you!

Re: QX4 doesnt start sometimes
Clean any corrosion on the battery posts and terminals and keep the connection tight. How old is your battery?

After you got the engine stated go home and test the electrics. Do it at home because when you find the problem you are in a safe place to fix the problem.
There is no room for error, thus there is no room for a wiggle of any connection to make things work.
To start: Verify the battery is being fully charged. A full charge by the alternator leaves the battery at 12.6 minimum voltage. Any lower you have a problem. The battery will range from 12.6 to 15 V depending where it is in charging.
All cables need to be secure, tight and CLEAN, all cables. All joints also, all ground connections via bolts need to be loosened cleaned then tightened and verified 0 ohms resistance to ground.
Once the battery connections are verified then the alternator must be checked at all RPMs. Then the combined efforts of the battery and alternator with the various loads in the car.
No assumptions, do a check of all systems
